The 3590 LMT under the category of Trip Planner - Trips cannot be removed.
Before anyone jumps in about other threads let me first say I have gone through all that pertain to the subject I could find.
With the Garmin connected to the PC I have gone to the internal storage under GPX and deleted all of the files. As one post suggested you also have to delete the temp.gpx. That is no where to be found on the device! I have searched for hidden files etc on the internal storage and it does not show up.
What I find disturbing is the fact that even if you use Base Camp you are not given the tools to clean out the storage and start fresh!
One would think that under under Garmin Express the tool may be there to clean out the old trip files.
If anyone has a clue how to clear off of the device I would really appreciate it.
Thanks,
Mike in MO!
